CiscoWorks Wireless LAN Solution Engine Software 2.7
Productivity and controlled spending are vital to profitability, which is why many organizations are seeking new ways to integrate their networks and critical business processes. But intelligent networks that do more than transport voice and data are crucial to success. One example is the Cisco® Structured Wireless-Aware Network (SWAN). Cisco SWAN helps to simplify the everyday operation of wireless LANs (WLANs), ensure smooth WLAN deployments, enhance security, and maximize network availability. CiscoWorks Wireless LAN Solution Engine (WLSE) is the intelligence behind Cisco SWAN. CiscoWorks WLSE centrally manages hundreds to thousands of access points within campus environments and branch locations.
Overview
CiscoWorks WLSE is a centralized systems-level solution for managing the entire Cisco Aironet® WLAN infrastructure. Advanced air/radio frequency (RF) and device management tools eliminate complexity and give administrators visibility into the WLAN.
By quickly and easily detecting, locating (Figure 1), and disabling unauthorized (rogue) access points, CiscoWorks WLSE helps ensure security, while ensuring that policies are consistently applied throughout the network. This advanced capability can benefit any organization, including those that have not deployed WLANs but still want to guard against intruders.
New in 2.7 is self-healing WLANs, an advanced radio management feature that enables a Cisco Aironet Series access point to adjust its cell coverage area automatically to compensate for an adjacent disabled or failed access point. CiscoWorks WLSE further optimizes performance by detecting and locating RF interference, while proactively monitoring utilization and faults.
CiscoWorks WLSE takes full advantage of the air/RF measurement and multifunction capabilities built into Cisco Aironet access points and a growing number of Cisco infrastructure devices that are part of Cisco SWAN. This reduces the total number of components needed in the network, and reduces the cost and the time needed for deployment, which is dramatically simplified with tools such as the assisted site survey.
In fact, CiscoWorks WLSE automates a range of previously time-consuming and repetitive tasks, such as bulk firmware updates and mass configuration of access points and bridges. CiscoWorks WLSE may be transparently integrated with other network management systems (NMSs), operations support systems, and CiscoWorks applications. CiscoWorks WLSE runs on the CiscoWorks 1130 for Wireless LAN Solution Engine hardware platform, which is one rack unit high.

Deployment
CiscoWorks WLSE speeds deployment by automating configuration and setup, reducing the overall cost to provision WLANs. The result is superior return on investment and enhanced productivity.
•
AutoConfig and AutoManage—Newly deployed access points may be automatically configured and added to the CiscoWorks WLSE list of managed devices using Dynamic Host Configuration Protocol (DHCP). This allows administrators to automate deployment and simultaneously maintain control in rapidly expanding environments. Cisco Aironet access points, bridges, and the switches to which they are connected are automatically discovered using Cisco Discovery Protocol.
•
Assisted site surveys—Complete and reliable WLAN coverage is achieved only with a detailed site survey. Site surveys are a "best practice" during deployment, and they should be performed regularly thereafter to address changes that occur dynamically in the environment. In the past, site surveys required special knowledge and were both expensive and time consuming. Most organizations contracted with outside consultants, but CiscoWorks WLSE enables IT managers to perform cost-effective site surveys in house without the need to hire individuals who are well versed in RF propagation and measurement. With the aid of the assisted site survey tool, optimal frequency selection, transmit power, and other settings are determined automatically and then applied by the administrator.
•
Mass configuration—Configuring a group with hundreds of devices requires no more effort than configuring a single device. Configuration tasks may be scheduled or executed on demand.
Operations
CiscoWorks WLSE automates a wide range of repetitive time-consuming tasks, simplifying the management of Cisco Aironet access points and bridges, resulting in enhanced productivity for network administrators.
•
Centralized firmware updates—Access point and bridge firmware may be updated in mass. Updates may be assigned to a specific device or to groups. Tasks may be scheduled or executed on demand.
•
Mass conversion to Cisco IOS® Software—Cisco Aironet 1200 and 350 Series access points running the VxWorks operating system may be upgraded in mass to Cisco IOS Software format. (RF management requires that access points run Cisco IOS Software).
•
Dynamic grouping—Groups make the network easy to understand and to operate. Devices may be organized into hierarchical groups defined by the administrator. Groups may span multiple subnets.
•
Configuration archive—The configuration archive stores the last four configuration versions of each device.
•
VLAN configuration—VLANs on access points may be configured and monitored, allowing differentiation of LAN policies and services, such as security and quality of service, for different users on enterprise and
public-access VLANs.•
Fault status—CiscoWorks WLSE provides a centralized tree view of all access points and device groups. Color coding and group icons indicate fault status. Faults may be filtered and sorted by priority to facilitate viewing and resolving problems.
•
Fault notification—Fault notification and forwarding are implemented with syslog messages, SNMP traps,
and e-mail.•
Switch monitoring—Switches connected to access points are monitored for availability and the utilization of ports, CPU, and memory.
Security and Wireless LAN Intrusion Detection
Wireless LAN Intrusion Detection System (IDS)—Organizations need to protect their RF environment and WLAN networks from unauthorized access. Rogue access points installed by employees or intruders create security breaches that put the entire network at risk. However, with Cisco SWAN rogues are quickly detected, located, and automatically shut down. Protection can be tailored to suit individual needs:
•
Integrated IDS—Standard Cisco Aironet access points are deployed with the radio (IEEE 802.11a, b, or g) placed in multifunction mode to service client devices and to provide WLAN intrusion monitoring. Intrusion detection information is gathered from the access points that scan the RF environment. Optionally, Cisco client cards and Cisco Compatible client devices provide additional information about the RF environment. Like Cisco Aironet access points, these clients have built-in RF measurement capabilities, which can provide an additional 10 to 20 times more RF measurement data than access-point RF measurements alone. Since WLAN clients can move freely about all areas of a building, rogue access points can be found in out of the way locations.
•
Dedicated IDS—A dedicated access point-only WLAN is deployed with the access point radio (802.11a, b, or g) placed in radio scan mode to support only WLAN intrusion monitoring. This solution provides continuous stateful 24-hour monitoring of the RF environment by access points dedicating their full bandwidth to intrusion detection RF monitoring. Unassociated client device monitoring is supported to minimize the risk of clients associating to rogue access points and to protect the network from malicious intruders probing the RF environment for weaknesses.
Other CiscoWorks WLSE security features include:
•
Security policy monitoring—All access points on the network are monitored for consistent application of security policies. Alerts are generated for violations and can be delivered by e-mail, syslog, or SNMP trap notifications.
•
Monitoring of 802.1X server availability—802.1X Extensible Authentication Protocol (EAP) servers, including Cisco Secure Access Control servers (ACSs), are monitored for response time. Cisco LEAP, Protected EAP (PEAP), and generic RADIUS authentication types are supported.
•
Secure user interface—CiscoWorks WLSE provides a secure HTML-based user interface that may be accessed anywhere, even through firewalls. In addition to the Web-based GUI, a Cisco IOS Software-like command-line interface provides direct console, Telnet, or Secure Shell (SSH) Protocol access to CiscoWorks WLSE for basic configuration and troubleshooting.
•
Role-Based Access Model—CiscoWorks WLSE has a flexible, role-based user access model. For example, help desk personnel can be limited to viewing reports and faults. Several common authentication modules are supported, including TACACS+, RADIUS, and Microsoft NT Domain.
Performance Optimization and High Availability
Interference detection and location is critical to maintaining a reliable WLAN. RF measurements sent to CiscoWorks WLSE include measurements for both 802.11 and non-802.11 interference. If the interference exceeds an administrator-defined threshold, a fault is generated so that the administrator quickly can locate and suppress the source of the interference.
•
Air/RF scanning and monitoring—Cisco Aironet access points are multifunctional, with built-in RF measurement capabilities. CiscoWorks WLSE analyzes these RF measurements, provides notification if performance degrades, and displays air/RF coverage (Figure 2).
•
Interference detection—CiscoWorks WLSE catalogues the physical location of all managed access points and creates a site map of the WLAN installation. This allows the wireless-aware network to detect points of interfering RF energy that affect network performance. The source of this unknown RF energy could be a rogue access point or a device that operates in the same frequency range, such as a 2.4 GHz cordless telephone or leaky microwave oven. Notification is sent when interference occurs.
•
Self-healing WLANS—If CiscoWorks WLSE detects that an access point has failed or is disabled, it compensates by automatically increasing the power and cell coverage of surrounding access points. The self-healing process provides contiguous coverage to maximize the available coverage of the WLAN. This process is designed to minimize the impact to WLAN clients.
•
Automated resite surveys—CiscoWorks WLSE automatically reassesses radio throughput and coverage and provides notification if performance falls below administrator-defined thresholds. New optimal settings can then be found by running the site survey wizard.
•
Warm Standby Redundancy—CiscoWorks WLSE supports both a primary CiscoWorks WLSE and a backup. If the primary fails, the backup CiscoWorks WLSE automatically takes over. Data is synchronized on a
user-defined interval.Figure 2

Reporting, Trending, Planning, and Troubleshooting
Real-time client tracking, together with a variety of predefined and custom reports, presents a powerful set of tools for troubleshooting and capacity planning. Using only a client name, user name, or MAC address, it is easy to determine to what access point a client is associated. Information about network utilization, client association and utilization, historical and current client usage statistics, Ethernet and radio interfaces status, and error details are displayed in both graphical and tabular form. Reports may be generated both at the individual device level and the group level. All reports may be scheduled, delivered by e-mail, or exported in CSV, XML, and PDF formats.
Integration
Integration with third-party NMSs is provided through syslog messages, SNMP traps, and an XML interface. As part of the CiscoWorks network management series of products, CiscoWorks WLSE integrates with the CiscoWorks LAN Management Solution and other CiscoWorks applications to maximize the efficiency of managing a converged wired and wireless network. Device inventory and credentials, for example, can be imported or exported between CiscoWorks WLSE and CiscoWorks Resource Manager Essentials (RME), an application that provides broad network management for a wide range of Cisco devices. If desired, device discovery may be turned off in CiscoWorks WLSE to allow automatic inventory synchronization with RME. CiscoWorks WLSE uses the same default user roles as RME, but it allows customization. CiscoWorks WLSE can be launched from the CiscoWorks Cisco Management Connection desktop, and conversely, it can be launched from the CiscoWorks Campus Manager topology map.
